The Suse copy shows only 'grub>' though I have no grub.cfg on the tftp
server nor did I install any modules.

On Debian grubarm.efi is only generated when you run grub-install and in
the generation process it adds the the relevant partition (msdos2). The
Debian package itself contains no file with an .efi extension.

Building upstream GRUB does not generate any *.efi file either. Instead
it behaves like Debian generating the *.efi file when installing GRUB on
the user chosen partition.

I wonder if it were not preferable to have the build recipe for GRUB and
the binaries on a denx.de server. Do you know the path to the Suse GRUB
build recipe?
